Reaction Steps

Using a procedure analogous to that described in Example 23, 4-chloro-6-methoxy-7-(2-(1,2,3-triazol-1-yl)ethoxy)quinazoline (160 mg, 0.52 mol) was reacted with 3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-5-one (120 mg, 0.63 mol), (prepared as described for the starting material in Example 10), to give 4-(5-(4-methoxyphenyl)pyrazol-3-yloxy)-6-methoxy-7-(2-(1,2,3-triazol-1-yl)ethoxy)quinazoline (105 mg, 44%).
